Diamond Grinder Tractor Trailer

Road smoothing is a practice of grinding the surface of a roadway to eliminate bumps and rutting while maintaining a proper profile by means of a diamond grinding mill. MDT chose the Townsend-North job to test this equipment as the road was structurally in good condition but was experiencing rutting and bump issues. The Diamond Road Smoother is a semi and trailer combo that moves down the roadway intaking information with averaging level arms and outputting a smooth road via the diamond grinding teeth on a revolving drum. Listed are a few resources of the equipment and construction projects using the equipment.
